Offset

The I/O mapped registers located here (F1BAR0+I/O Offset 50h-FFh) can also be accessed at F0 Index 50h-FFh. The pre-

50h-FFh

ferred method is to program these registers through the F0 register space. Refer to Table 6-29 "F0: PCI Header/Bridge Con-

 

figuration Registers for GPIO and LPC Support" on page 190 for more information about these registers.
